REED CITY, MI — A former Mecosta-Osceola County Intermediate School District teacher was sentenced to at least three years in prison this week after being convicted of charges relating to having sex with a student.

Janet Brown, 34, of Evart was sentenced in Osceola County Circuit Court on Friday, April 24 after her conviction in March on one count apiece of criminal sexual conduct in the third degree and fourth degree, according to UpNorthLive.com.

She received between 3 and 15 years in prison.

Brown was originally arrested in November 2012 after investigators alleged she had sex with a 16-year-old male student at the Ashmun School on the Eagle Village Youth Detention Center's campus near Hersey.

The school is a collaboration between the Mecosta-Osceola ISD and Eagle Village, which serves troubled youth with counseling and residential treatment programs.

According to the Cadillac News, the relationship was uncovered when the teen was found with a cell phone used to arrange meets at Eagle Village, where students are not allowed to have personal phones.

Brown testified her relationship with the teen "crossed the line" and that she tried to rebuff the teen's sometimes "aggressive" sexual advances, according to the News.
